Delphi was awarded a contract to develop the real-time software architecture for the Sonar Signal Processor (SSP) portion of the Hughes Common Torpedo Processor (CTP). The SSP is comprised of anywhere from 3 to 6 Octal C40 Boards for a total of 24 to 48 DSPs per system.

Delphi was responsible for the selection of TMS320C40 multiprocessing software tools and real time operating system for the Octal C40 Board. This included participating in the development of software and interface requirement specifications as well as the complete design and development of an Application Programming Interface (API) to support multi-processor communications, system I/O, hardware interfaces, and data conversion utility libraries. In addition, Delphi developed all Built In Test (BIT) and Fault Detection and Isolation (FDFI) routines to support system test and diagnostics.
